摘　　要：利用无人机摄影测量技术监测公路工程进度成本低,灵活高效。然而,现有的监测方法主要用于识别地面变化和提取变化范围,无法直观、定量地分析工程在不同阶段的进度,不能满足对工程进度准确监测的要求。结合公路建设的特点,本文提出了一种基于地表覆盖转移矩阵的公路工程进度监测方法,利用无人机低空摄影获取影像数据,提取并分类监测工程范围内的地表覆盖信息,基于空间转移矩阵定量分析地表覆盖变化和转移情况。主要过程包括数据预处理、工程地表覆盖提取与分类、工程进度分析。该方法应用于S312省道工程进度监测中,取得了良好效果。UAV photogrammetry is a flexible,efficient and fast way to monitor the progress of highway engineering with low cost.However,the existing monitoring methods are mainly used to identify the ground changes and extract the change range,which can not intuitively and quantitatively analyze the progress of the highway engineering in different stages,and are not accurate enough.Considering the characteristics of highway engineering,we propose a monitoring method based on engineering land cover transfer matrix,which uses low-altitude UAV photogrammetry to obtain images,extracts and classifies the engineering land cover information within the monitoring range,and quantitatively analyzes the change and transfer of engineering land cover based on spatial transfer matrix.The main process includes data preprocessing,extraction and classification of engineering land cover,and analysis of project progress.Finally,the method was used to monitor the provincial highway S312 project,and achieved good effectiveness.
